I have a couple of ether ten R3 boards but they don't have the MAC address chip on them and I am having trouble getting the sketch to work by applying a MAC address manually. Does someone have a version of the sketch configured for manual MAC address that works that i can copy and run.

I got this from superhouse.tv I think. It came from a link by Jon Oxer somewhere...

/*
* Retrieve the MAC address from a Microchip 24AA125E48 I2C ROM, and report it
* to the serial console at 57600bps. The I2C address of the ROM is set to 0x50,
* which assumes both the address pins are tied to 0V.
